Product Summary

A counterweight check valve is a sophisticated plumbing device that reacts to changes in the pressure of the delivery water. Typically, both hot and cold water sources are fed into a pressure balance valve, and its job is to ensure that the volume of water that leaves the counterweight check valve is a constant mix of these two sources, even if the delivery pressure of the two sources changes. This is very important to keep the temperature of your shower constant even when the supply is not.

A counterweight arrangement for mobile vehicles including a pair of transversely spaced support members having notches formed therein. The counterweight check valve has a pair of transversely spaced rod members secured thereto which is selectively received in the notches. The cables are received around corresponding sheaves which may be repositioned to control the movement of the rod members into and out of the notches and around the support members.
